CompactLog – Solving CT Scalability with LSM-Trees


RFC6962 certificate transparency log with LSM-tree based storage - Barre/compact_log

CompactLog implements the RFC 6962 Certificate Transparency API on top of SlateDB to explore how LSM-tree storage can address traditional CT log scalability challenges. Accepts X.509 certificate chains and pre-certificates Issues Signed Certificate Timestamps (SCTs) Maintains a cryptographically verifiable Merkle tree Provides inclusion and consistency proofs Stores data in cloud object storage (S3, Azure Blob) or local filesystem Many CT log implementations have a Merge Delay (MMD) of minutes to hours, where submitted certificates aren't yet included in the Merkle tree.
